Specification of Letters Patent.

Patented Oct. 6, 1914;.

Application filed June 10, 1913. Serial No. 772,809.

To (ZZZ whom it may concern 7 Be it known that I, Znxos PORTER, acitizen of the United States, residing at Holliday, in the county ofSalt Lake and State of Utah, have invented new and useful Improvementsin .Plows, of which the following is a specification.

This invention relates to plows, and it has particular reference towalking plows of the reversible type.

One object of the invention a reversible walking plow wherein a baseconstituting a land side bar supports an up-- right about which a sleeveconstituting standard rotates, said sleeve or standard be-' ingassociated with the beam, the handles and with a locking lever.

A further object of the invention is to produce a plow of the typedescribed wherein the right and left hand mold boards are provided withhingedly supported wings and with means for reversing the position ofsaid wings when the beam and the handles are reversed.

Further objects of the invention are to simplify and improve theconstruction and assembling of the parts of the device.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawings,Figure 1 is a top plan view of a plow constructed inaccordance with the invention. Fig. 2 is a side elevation of the samewith parts broken away. Fig. 3 is a top plan view, showing the device intheactof being reversed. Fig. 4 is a plan view of the base portion ofthe device. Fig. 5 is a detail view in side elevation showing the sleeveor standard carrying beam, detached. Fig. 6 is a rear elevation of thesame. Fig. 7 is ahorizontal sectional detail view taken on the line 77in Fig. 2.

Corresponding parts in the several fig- I ures are denoted by likecharacters of reference.

The base bar 10 is formed with frogs, 11

adjacent to the ends thereof upon which the .mold boards 12 are boltedor otherwise secured. The base plate 10 may in itself coustitute thelandside bar, or a wear plate 13' constituting the landside proper maybe secured thereon by means of bolts 14.- which also serve to secure inposition adjacent to the furrow side of the base member 10 a tubularupright 15 which is provided with flanges 16 for the passage of theconnectmg bolts. The upright 15 has an ofl'setl? on whichv a sleeve orstandard 18 is stepped for rotationabout the upright; the latter belngthreadedat its upper end, as shown, for the reception of a cap member 20which, after the parts are assembled may be secured by one or more keys21. The plow beam 22 is associated with the sleeve or standard 18 fromwhich it extends in what maybe regarded as a forward direction, saidsleeve or standard being provided on its rear side with lugs 23 tosupport a lever 24 which is fulcrumed between said lugs on a pin orpivot member 25. The sleeve 18 is also provided with rearwardlyextending divergent arms or brackets 28 upon which the handles 27 aresecured. Beneath the arms 26, the sleeve 18 is provided with arearwardly extending arm 27 having an upwardly extending lug or crosspiece 28 and a transverse notch 29, the purposes of which willbehereinafter explained. The lever 24 is formed with a crank member orextension 30 which constitutes a, locking member and which is adapted toengage either one of two oppositely disposed slots 31 formed in the capplate 20, thereby serving to secure the sleeve or standard carrying theplow bers 34, 35 which are extended to form hinge member-s36, 37, thelower hingemember "being considerably longer than the :upper mold boards12.

the other mold board in an out-'of-the-wa'y -'and"unobstructingposition.

look or securing including a cap member 41 having anup-= wardly'extending eye 42 and provided at;

, one end with a downwardly extending slot-1 ted-orbifurcated bracket 43wherein a lever 44 is mounted on a pivot member 45.;

One end of the lever member 44' is loosely pivoted in the notch 29 ofthe arm 27 by a pivot member 46; the other end of the leverl member44 isbifurcatedfor the reception of;

one end of a brace member 47. The other: end is pivotally connected"with the wings 33;; at the juncture of the top edges of the lat-i ter,said brace memberbeing pivot'ally'con. nected with the lever member 44by a pivot;

. member 48. The parts, of course, are so pro-;v

portioned that when assembled the combined length of the lever member 44and the brace member 47 will be exactly rightto hold the wings inposition, as clearly indicated in, Fig. 1;, The eye 42 of'the cap member41 is connectedwith the lever 24 by means of a link 49 which is ofsuch'length that whenthe locking member 30 of the lever 24 is inengagement with one of the slots 31, the? cap member 41 will be seated uv on the crossbar 28 of the arm or bracket 2 thus serving to lock thewings in adjusted position.

When it is desired to reverse the plow, the

lever 24 is manipulated to disengage the locking member 30 from the slot31 with which it is engaged, at the same time lifting and unseating thecap member 41 from the cross bar 28. The standard or sleeve is now' freeto rotate about the upright 15, being swung around by the beam while theoperator walks along with the handle. Owing to the different length ofthe hinge members 36, 37, the mold board wings, when in positionfor'operation, will gravitate to a slightly tilted position from which,when the device is reversed, they will be displaced by the action of thejointed brace 44, 47, the joint of said brace breaking so as to passclear of obstructing parts, and the pull on the braceserving tostrengthenthe latter when the partshave"been'reversed; The? lever 24 is.then manipulated to cause the locking member 30 to engage a slot 31',and

by the same operation the cap member 41 is replaced on the cross .bar24, thus locking i the mold board'wings securely in position.
